Goddard
About the only thing I remembered about Robert Goddard was that he worked on a liquid fuel rocket and this picture:
But thanks to another interesting Young Indy doc I now know more (for example that he was follically challenged like Wilbur Wright):

Goddard's paper as published by the Smithsonian:

As I've said before I really like these Young Indy documentaries, bite sized bundles of historical knowledge. I didn't know that Goddard was so secretive and patent crazy. Also, didn't know that he worked near Roswell, NM, that fabled place.
